城市灾害应急能力评价研究

城市灾害应急能力评价是城市灾害管理的重要内容，建立城市灾害应急能力评价体系对增强城市灾害管理能力和提高政府部门对灾害的应急响应能力有极其重要的意义。文章从系统理论的角度出发，运用层次分析法（AHP）和专家词查法合理地确定了各个评价指标的权重，建立起城市灾害应急能力评价模型。该方法将定量和定性相结合，很好地解决了城市应急能力的定量评价问题，同时，还可以克服主观随意性，从而提高对城市灾害应急能力评价的可靠性、准确性和客观性，为城市安全减灾提供科学依据。     

煤矿高浓度胶结充填系统可靠性评价研究

煤矿充填系统可靠性受多种不确定因素影响.通过对影响东庞矿高浓度胶结充填系统可靠性主要因素的分析,综合考虑各因素随机性、模糊性特点,利用层次分析法(AHP)建立充填系统可靠性模糊综合评价模型并确定各指标因素权重,运用模糊数学理论确定隶属矩阵和模糊综合评价法得到充填系统可靠性综合评判向量,按照最大隶属度原则确定此充填系统可靠性为“较稳定”等级.经充填工业性试验开采验证,系统可靠性模糊评价模型的建立是合理有效、结果符合实际情况的.     

航运企业安全管理体系有效性评价研究

定期评价安全管理体系的有效性既是ISM规则的强制要求,更是航运企业持续改进安全管理体系,提高体系运行质量的重要手段,但目前不少企业在管理实践中对体系的有效性评价大多采取定性的方法,难以保证评价结果的客观性和科学性。通过安全管理体系有效性内涵及其表现特征的分析,将体系运行有效的符合性、目标性、适宜性、充分性和文化性5个表现特征作为一级指标,并进一步细化得到24项二级指标体系,采用层次分析法确定各指标的权重,以实例验证,为航运企业实施安全管理体系有效性评价提供科学、客观、有效的方法。     

中国城市垃圾典型可行焚烧技术的综合评价

中国城市垃圾处理的主要方式正在由卫生填埋向垃圾焚烧转变. 基于中国城市垃圾焚烧处置需求特征分析,建立了技术评价指标体系,采用层次分析法,从技术的可靠性、经济性和适用性三方面,对国内外现有4种主要城市垃圾焚烧技术进行了综合评价. 结果表明:流化床技术和层燃技术在技术成熟度、技术能力和二NFDA1英污染控制等方面相对可靠,适用于我国多数大城市的垃圾焚烧处置. 国产流化床焚烧技术更加适应当前国内垃圾分类水平较差的大部分城市;层状焚烧技术则比较适用于城市垃圾管理水平高、垃圾分类较好、热值较高、垃圾处置集中度高和规模较大的城市;旋转焚烧和热解焚烧技术则较适用于垃圾成分复杂、尺寸不均匀的小城镇、工业园区垃圾处置或医疗废物处置,但二者均需加强二NFDA1英排放控制.      

城市天然气管道风险特征与肯特法的改进

根据城市高压天然气管道特点,将适合于城市天然气管道风险分析的肯特评分法加以改进,包括调整评分项目和事故因素权重,使其成为适于城市天然气管道的风险分析法。将改进后的肯特评分法应用于常州21km高压天然气管道的风险评价,得出8个相对高风险管段,其分析结果可作为安全管理人员合理分配维护资源的理论依据。工程应用实例证明:改进后的肯特法具有较强的可行性,是城市高压天然气管道风险评估的有效工具。     

A multiple criteria evaluation of sustainable agricultural development models using AHP

Selection of the appropriate agricultural development model has become an important issue in Iran. Using data from Fars province of Iran, the purpose of this paper is to use analytic hierarchy process (AHP) for selecting between the two competing sustainable agricultural development models, which have been developed based on the general tenets of Ecological Modernization (EM) and De-Modernization (DM) theories. Farmers, environmentalists, board members of rural cooperative, rural women and experts from Fars Agricultural (Jehad-e-Keshavarzi) Organization participated in application of AHP to this study. They applied AHP to determine the priority of DM and EM based sustainable agricultural development models. Each group determined the priority of the two models for sustainable agricultural development. The findings indicated that ecological criteria i.e. wise use of resources, environmental protection and product quality are the most important criteria for sustainable agriculture of Iran, followed by economic criterion employment and social criterion participation. A sensitivity analysis was carried out to determine the critical factors that affected the priority of alternatives. The results indicated that EM-based sustainable agricultural development model has a higher priority as the theoretical base of agricultural development of Iran.

黄河三角洲土地资源开发对策的探讨

黄河三角洲是我国三大三角洲之一,面积约5930km²,它拥有丰富的土地资源,但从大农业角度来看,其土地质量较差,生态环境脆弱。当前,其土地资源的合理开发利用具有十分重要的现实意义。 首先,本文将区内土地类型划为 5类和19个亚类。其次,应用二级模糊综合评判,将其土地质量分为8等13级。其中宜农地占28.83％,宜牧地占34.44％,渔业用地占27.98％。最后,应用层次分析法（AHP）对土地资源合理开发利用的对策作了分析探讨。认为:对于黄河三角洲土地资源的开发,必须强调遵循经济效益服从社会效益和生态效益的总原则。在此前提下,提出了以保证工矿业用地为首的6项开发策略,以及以引黄放淤改良盐碱地为首的20项开发措施。

A framework based on fuzzy AHP-TOPSIS for prioritizing solutions to overcome the barriers in the implementation of ecodesign practices in SMEs

Small and medium enterprises (SMEs) are under pressure to adopt sustainable practices in their business due to increasing environmental challenges. This study aims to identify and prioritize the solutions to overcome the barriers in the implementation of ecodesign practices in SMEs. This study helps the companies to develop and implement the strategies on priority using higher ranked solutions. In this study, a framework is proposed that is based on fuzzy analytical hierarchy process and fuzzy technique for order preference by similarity to ideal solution to rank the solutions that overcome the barriers in ecodesign implementation in SMEs. The proposed framework is illustrated by conducting a case study of an Indian ring and piston manufacturing company. This framework provides an effective support in the decision-making of the company for producing eco-friendly products through the implementation of ecodesign practices. Results of this study emphasize that training of designers to use different ecodesign tools is an essential practice for SMEs.
